Mounted on the crossinemheis tie supporting frzimfe,

the window sill as shown :2 :iml 3'; all (lively, are 102 .1?13! hem ngs 8 and 9, mm mlnnled in heari: L s a SlGGYi) or tubular shaft i0, 111?; Carrying atils uterl 11 yoke ll. epresents a cross-head having real-- Wardly projecting arms 13 which are pivot ed m l-5 to the :fOl'lii- 11 (see Fig. l), and exiencling relirninwlly an l l loivnwarclly win (he upper @1111 of said emssheml is an arm l to which one end of the comm-(ling roll 15 is pivulei'l at 14., the up posiie iIlCl of said mmneling rod being PlYOlQLl at 16 to iihi; huncl lever 16 which is bifurcated at iis lone? end and pivoted at 16 to the tubulni' shafi l0 :li a point near the rear end tlierenf.

Lying ii'iihin the sleeve 01' hollow shaft 10 is a solid shaft 1%) carrying at one end :1 rank arm, while the opposite end of sail} shaft is (tonnecietl through lhe medium Of an oi'ilinury universal joint composed of men) hers Q2, :23 and 2 3 as elearly shown in Fig. 5, to {he grooved pulley Qijournalecl on the sincl 24 of the brass-head l2, {whereby a flexible connection is effected at 5 point on a horizontal line with the pivotal (:(mnel'linn between the yoke 11 of the shift 10 and lhe arms 13 of ilw cross-head 12, enabling said cross-head to he tilted to an angular position, as shown in Fig. 2; through the medium of the hand lever 16 and its connecting rod 15,

Mounted in parallel ways 12 of the crossheacl 32 is- A mast or me? 17 in the form a channel mil, an attached at poinis near l ie e ends of said staii through the are the. opposite encis of High n" 18 :1 cable 18. which, u fenclmg through the GYICE anchored or seeill'ml in a guide ways 25 and 26 of the cross-head 12, is pure about the pulley 21, as shown in Fig 4 and 5.

it will be seen that the cable is so rove about the pulley as to enter and leave the groin-in of said pulley at one side thereof, as shown in Fig. 3, whereby as the shaft 19 is rotated through the medium of the crank arm 20, revolving the pulley 21 through the universal coupling as described, the cable will be caused to wind onto and unwind from said pulley, causing the staff to travel lengthwise within the uide-ways 12 of the cross-head as the pul ey 21 is rotated in either direction.

Mounted on the upper end of the staff 17 is a brush, sponge or other suitable cleaning agent 27 which is pivotally carried upon the socket arm 28 that. receives the tapered upper end of said staff, said brush being flexibly held in a vertical position through the medium of the hinge 29 and the tension of the spring 29*, one end of which is secured to the back of the brush, whilethe free end overlaps the hinge and bears upon the socket arm 28, as shown in Figs. 2 and 5, whereby said brush is permitted to retain a vertical position through the action of said hinge and spring as the mast 17 is tilted through the medium-of the lever 16 and the connecting rod 15, when said brush is brought against the outer surface of the window pane, as shown in Figs. 1 and 2.-

A tube 30 is inserted through the back of the brush, communicatingwith the bristles thereof and extending outwardly from the brush back in the form of a sleeve or nipple to receive a hose connection to provide for a source of water supply to the brush 27, as shown in Figs. 2 and 5.

It will be seen from the foregoing arrangement and construction that the device, when secured in position upon a window sill, may be so controlled and operated through the lever 16 and crank armQO as to cause the brush or cleaning agent to be raised and lowered by the mast through the action of the cable in winding upon and unwinding from the pulley when rotated in either direction by the crank arm 20. Said brush may also be swung horizontally in the arc of a circle across the window pane by imparting an oscillatingmotion to the lever 16, which in turn will rock the hollow shaft 10, carrying with it the cross head and its mast, while a reciprocatory motion imparted to the lever 16 will, through the connecting rod 15, cause the cross-head to rock upon its p1votal hearing, with the yoke 11 carrying the brush I cause the brush or cleaning member carried on the end of the mast to cover the entire plane or surface of the window pane, when either or both sash may be treated by raising or lowering eithersash to make it ac-. cessible for ease or convenience in the operation of cleaning.

While provision is made for the attachment of a hose to convey water to the cleaning member, it will also be desirable to employ at the upper end of the mast a scraper or wiping member for the purpose of drying the window glass, and for this reason the brush shown is made detachable so as to permit its removal and the substitution of 1 any other suitable agent therefor.

"The principal features in my invention lie in the construction and association of the several parts in such manner as to secure through mechanical action the manipulation of the mast, with any suitable cleaning agent or member mounted thereon, so as to enable the entire surface of the glass to be covered or gone over by the operator of the device from a point of safety within the building.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is:

'1. A device for cleaning windows com prising a supporting frame, means for detachably securing said frame to the window sill, a sleeve journaled in hearings on said frame, a cross-head pivotally mounted on said sleeve and having a parallel way formed therein, a stafi movably carried in said way, a lever pivoted to said sleeve, a 100 rod pivotally connecting said lever to said cross-head, a shaft journaled in said sleeve,

means for connecting said pulley with said staff, and means for rotating said shaft to impart a reciprocating motion to said staff.

2. A device for cleaning windows com prising a supporting frame, clamping members for detachably securing said frame to a window sill, a sleeve journaled in bearings on said frame, a yoke carried on said sleeve, a cross-head pivoted to said yoke and having a parallel way formed diametrically therein, a staff mounted to slide in said way, a lever pivoted to said sleeve, a connecting rod pivotally attached at one end to said lever and at its opposite end to said cross-head, a shaft journaled in said sleeve, a pnlley-journaled in. said cross-head 12 and having a flexible connection with said shaft, a cable rove about said pulley and having its opposite ends attached to opposite ends of said staff, a crank attached to said shaft for rotating said shaft'and pulley to raise and lower said stafi',"*aclean'ing member detachably mounted on said staff;

3. A device for cleaning windows con-. sisting of a rectangular supporting frame composed of parallel side members and 3 having cross members attached to the ends thereof, depending brackets attached to the ends of said side members, clamping cleats engaging the eppnsite faces of said side members, means for drawing said cleatsintn fixed conflict with said members, journal bearings meunted. 011 said frame, a sleeve journeled in said bearings, 2L yoke carried on one end of said sleeve, a crass-heed pi\" oted to said yoke and having a parallel Way formed diametrically therein, a stall slidingly mounted in said "Way, a lever pivoted to said sleeve, a connecting rod pivotally at tached at one end to said lever and at i3s opposite end to said cross-head, a shaft journeled in and extending through said sleeve, 11 puliey jeurnaled in said cross-head,

a universal coupling cnnnec'ting said pulley with said shaft, a cable rove about said pulley and passing through guide-Ways in 20 said cross-head, the opposite ends of said cable being attached to Opposite ends of said seed, a crank attached to said she. in rotating said shaft and pulley to impart recipmcaiing niolion to said staff, and cleaning member flexibly and detachably mounted on said staff.

In testimony wnereof, I sign this specification in the presence of two witnesses.
